Pelly pull-out frame - distance between

[turbo100]

Hello,
I have purchased a couple of brackets and wall rails at Jem o Fix by the brand Pelly.
I may later add pull-out drawers and am considering this one:

Anyone know the CC measurement between wall rails for this to fit?
I can't find the info on Jem o Fix's website or elsewhere (but I am admittedly terrible at finding things online).

So, it's the CC measurement for the wall rail in this installation I'm seeking:
